iM-PRovE-MENT iN MACHINES Fon 'reNoNxlNG sPoKes.

. Be it known that I, JOHrFVV. HUFEMA, of" 'Fremont, in the county ofSteubenandStateof Indiana,

haveinvented a newand useful Improvement in a` Spoke-.Tenoning Machine;and I do declare that the Jfbllowing is a true and,` accuratedescription thereof',

`reference being had t0 the accompanying drawing and to the letters 'olreferencemarked thereon, and being a part of this specificationpinwhich- Figure 1 is a perspective view of my machine, i'om thefront,.andA

Figure 2 is asimilar` view, from the rear. Like lettersindicatelikepartsain cach figure.

'lhe nature of this 1invention relates to the conl struction of amachine for tenonin g the en ds oi'. spokes, fitting them to enter`the.mortises in the hub'of a wheel.

. `Ilz-consists inthe general arrangement of.tl1e.vari' ons parts, asmore -fully hereinafterset'forth;

A represents a table, supported by a proper frame. l Bis a stationarystandard,` erected at the rear end of the table, "at thesidefoi? au`opening therein.

B is a similar standard, movable, in `the opposite 'side of the` openingin the table, having a` tenon projecting down through it.".lllis'standard is secured thei'einiby a key, (t, as shown in fig. 2.

The standard B' is held parallel with the' other by a screwrod,` b,passing through its ange, and en- 4 C C are sections'of a cross-head,secured together l by screw-rods c, and moving vertically in slides inthe inner faces of the standards; theyhave, interposed between 'them the`wedge-shaped`key D, which, when y driven down, spreads the section Caway from the other, l E E are'cutters, lin the form of a shoulderedchisel, and sloped on the cutting-edge, to givea` drawing cut; eachchisel forms or shapes one side of the tenon. j

vF is a treadle, pivoted under the table, and to 4which .the cross-headis connected, by a rod d, by

means of which the crosshead is drawndown.

G is an arched rod, erected on the standards, hav- Vinga spiral spring,H, suspended from it, Awhose lower end is secured tothe cross-head, tojdraw the latter` up from'the table, when -the treadle is released from.

the footyoi" the operator-` l VI is a'gtemplet, secured tothe table, atthe edge of the opening, thevcutter E passing in close proximity toitsedge.

Iisasimilar templct, but secnredto and moving with the standard B'.

` J `is a gauge, on the table, to guide the operator in Vplacing. ,1fthe rspoke to be tenoned, which, being in position, he pressesdown thetreadle, bringing down theV cross-head, whose chisels vheilig secured ina recess in the inner lower corners of the sections, shear oli` thewood, and thus form the tenon, whose'thi'ckness equals the distancebetween the chisels.

lo increaseuthe thickness of the tchou, loosen the screwrod b and keyand` move ont the standard B, Vsecuring as before; then .loosen thescrews in the cross-head,4 and drive the wedge to spread the sec-` tionsand their chisels apart, land secure as before described.

What I claim as my invention, and desire to secure by Letters Patent, isU The vcross-heads G C', the -wedge D; the standards B B', andscrew-rods b and c, with the spring H, 'the yoke G, the chisels E E',the templets I I", thc rod d, treadle F, and guide J, all in connectionwith a table, A, when constructed and arranged as described and shown,and as and for the purposes set forth.
